Here’s the thing about What Became of Jack and Jill? — you can’t even call it a slow burn, because that would imply there’s eventually a fire. This 1972 British psychological “horror” film — and I’m using the term out of pity — attempts to blend generational warfare with suspense, but winds up as a glacially paced morality play where the moral is, apparently, “Don’t trust mod sociopaths who spend more time combing their hair than plotting believable crimes.”
The Plot: Gaslight, Gatekeep, Grannykill
The plot is so simple it should be criminal — and ironically, it is. Callous pretty boy Johnnie Tallent (Paul Nicholas), a smug slab of Swinging London apathy, lives with his invalid grandmother, Alice, hoping to coast into a small inheritance and a free house. But because Amicus Studios wanted to go “edgy,” Johnnie doesn’t just wait for nature to take its course. No, he and his girlfriend Jill — a smirking misanthrope and travel agent who would burn an orphanage if she could get a tan from the flames — decide to gaslight poor Granny to death.
Their plan? Convince Alice that a youth-led fascist uprising is afoot, designed to wipe out the elderly. If that sounds like a sharp social satire, think again. It’s less Lord of the Flies, more News of the World meets prank phone calls. Johnnie limits her access to newspapers and TV, invents fake youth rebellions, and even stages a parade — which is somehow supposed to pass as a death squad. It’s psychological horror boiled down to “let’s traumatize grandma with slogans and graffiti,” and the result is neither scary nor particularly intelligent. It’s just… mean.
Eventually, Alice — who’s the only sympathetic character in this debacle — succumbs to fear and has a heart attack. This is the movie’s high point, which should tell you everything you need to know.
The Tone: Horror, Without the Horror
Let’s be clear: Jack and Jill isn’t scary. It doesn’t build tension; it builds resentment. The cruelty is flat and one-note. There’s no stylistic flourish, no suspenseful cinematography, and not even the schlocky exploitation fun Amicus was allegedly aiming for. The camera sits as still as Alice, watching Johnnie and Jill smugly scheme like they’re auditioning for Coronation Street: The Psychopath Cut.
This could’ve been a modern Diabolique or a twisted take on Arsenic and Old Lace. Instead, it’s like being locked in a room with two morally bankrupt youth leaders and watching them whisper mean things at a pensioner until she dies.
The Performances: Ice-Cold or Half-Baked
Paul Nicholas, usually seen with a song in his heart and a perm on his head, turns in a performance as Johnnie that feels like an AI trying to simulate “detached cruelty.” Vanessa Howard, as Jill, smirks her way through the movie like she’s playing Cruella de Vil’s niece on sedatives. They’re both too pretty and too vacant to be truly sinister. They’re not terrifying — they’re insufferable.
Mona Washbourne as Alice, meanwhile, delivers the only performance with any real emotional gravity, which makes the entire experience more painful. Watching her descent into terror feels like emotional elder abuse in cinematic form. There’s no catharsis. No poetry in her suffering. Just 100 minutes of mental torture.
The Message: Youth Is Wasted on the Psychopaths
Director Bill Bain called the film “a savage indictment of the shallow education young people get today.” That’s rich, considering this is less indictment and more accidental advertisement for euthanasia. The movie is so joyless, so miserably bleak, that you begin to wonder if the actual message is: everyone deserves to die, just at different speeds.
Even the twist ending — where the inheritance turns out to come with strings attached and Johnnie and Jill turn on each other — lands with a wet, cynical thud. Jill gets stabbed, Johnnie collapses into a blubbering mess, and not one viewer is surprised or even remotely moved. It plays less like Shakespearean tragedy, more like two spiders fighting over an empty snack bag.
Direction and Production: Shepperton Studios Deserved Better
This was supposed to be Amicus’ edgy pivot into exploitation. Instead, they were so disturbed by their own product they offloaded it to 20th Century Fox like a haunted VHS tape. The cinematography is flat, the pacing is molasses-slow, and any attempt at stylish flair dies somewhere between Johnnie’s sneer and Jill’s hair flip.
Even the original title — Romeo and Juliet ‘71 — suggests a film that thinks it’s about doomed young lovers. But these are not lovers. These are sociopaths you’d ghost after one Tinder date.
Final Thoughts: A Grim Sit Without the Payoff
What Became of Jack and Jill? answers its own question: they became deeply unpleasant people in a deeply unpleasant film. It’s not suspenseful, it’s not horrific, and it’s not even exploitative in a way that might provoke or entertain. It’s like watching two entitled millennials commit slow-burn elder murder for pocket change, only to be undone by the fine print.
It’s not horror. It’s not satire. It’s not even particularly interesting.
It’s just sad. And boring. And a little bit cruel.
Rating: 1 out of 5 poisoned tea cups
Because despite the premise and the promise, this is one film where the only scary thing is how long it drags on.
